Observation 52076: Agaricus xanthodermus Genev.

When: 2010-09-05

Collection location: Bemidji, Minnesota, USA [Click for map]

Who: damon brunette (damonbrunette)

No specimen available

Im getting a little confused by the yellowing on the agaric descriptions. I may have not been thorough about my observing. I rubbed the stalk on these to produce the bright yellowing. I didnt try it on the stem, as i was not aware that may have been an indicating factor. They were growing in sandy soil in grass. The stems were very smooth, curved, and bulbous at the base.
Whoever changes the name on this, please comment about the main indicator you would use, thanks.

You need more info to ID an Agaricus.
Odor – almond, mild or foul like road tar.
Bruising reaction – slow, quick, color, fading or changing intensity.
Base of stalk is a good location for a bright yellow color with A. xanthodermus.
Tree type or only grass helps with some species.
Best to use a regional key to your area for this genus.
